There is a fly in the udder ointment. IF you are sending messages related to the running of your farm operations, you cannot use Amateur Radio frequencies. A message like "the disc harrow is broken" is not acceptable while a message like "lunch is ready" is OK.

I agree on the type of message being transmitted. Same type of comms that we would normally do when using ham frequencies and HT to HT units. I will need to test, but hopefully we I can accomplish 2-way messaging.

In the 1970s, when pagers were more common (and cell phones were in R&D labs), a few radio amateur clubs looked at POCSAG to alert amateur radio WX and severe weather/tornado spotters (NWS VHF broadcast stations were just starting construction).

At that time, as I remember, FCC said NO. Support from St. Louis and Peoria NWS did not help to change FCC opinion/decision (Part 97.111(b)). It was not considered emergency communications.Since the 1970s, the FCC has been more specific in the types of one-way communications permitted.

can anyone help me out, im good with this stuff but i have been out of the loop for a long time. i have been dieing to built something like this for fun.im having issues with figuring everything out. can anyone help me with a parts list or contact the guy that posted it.

ALl the talk of legalities.. This isn't much different than APRS. Lots of transmit only APRS stations out there. Lots of people (control operators) putting a APRS pod onto something being operated by a non-licensed person (or even totally automated: balloon payloads). The theory is that there's no requirement for the control operator to be physically next to the transmitter (otherwise, how to run a repeater), and it turns out there's no requirement for a particular response time from the control operator. If officialdom says "turn it off", the control op has to be able to do so, but there's no "control shall have a maximum latency of 10 millisecond" kind of rules.

I think ultimately it comes down to the basic "rude rule". If you are inconsiderate or rude, then you're breaking some rule. If you do something, and nobody complains, you're probably legal.
